hey guys I recently just got a Powermac G4 Quicksilver 733mhz for $50. Its got 1.25 gigs of ram and two 40 gig HDs ( I added a second one). The video card is nothing special and I wan the most jacked video card i can possibly load into it. I have found some G4 4x AGP card on ebay that are mac certified that will work but being a person that likes to mod stuff and a person who is going to be an engineer I figured I get me a PC video card and flash the ROM and make it work in my G4. after I get this G4 card I'm gonna get a Sonnet Tech ST G4 1.8ghz.

A 7800 GT would outperform any other AGP card you can flash to mac. Although, with cards like these, the bottle neck isn't the card but the machine. You would probably be wasting money if you put such a high end card in a QS. The Quicksilver just can't keep up.

Try this site to get an idea of cards that would work:http://themacelite.wikidot.com/compatibilityThen go to the "Downloads" section and you will see the Core/Memory Speeds and RAM size/type for each card.I use GeForce 6200/256MB cards in most of my older Macs. It is a "mid-range" video card upgrade, not the most impressive card available, but they are inexpensive & easy to flash; they have QE supported and Core Image Hardware Accelerated. With a small GPU fan replacing the passive heatsink mine run at about 35 - 40 degrees (C).
